W artykule przedstawiono nowy algorytm do estymacji parametrów składowej podstawowej sygnału prądu wtórnego przekładnika prądowego zniekształconego na skutek nasycenia rdzenia magnetycznego. Opisywany algorytm został zaprojektowany przy użyciu innowacyjnej, metodologii, w której pobrane próbki prądu wtórnego traktowane są jako współrzędne wektora umieszczonego w trójwymiarowej przestrzeni. Badania symulacyjne wykonane z wykorzystaniem ATP/EMTP potwierdzają dużą skuteczność proponowanego algorytmu.

In the paper a new algorithm is described that is intended for estimation of fundamental component parameters of the distorted secondary CT current due to magnetic core saturation. The algorithm presented was derived with use of the innovative methodology where the current samples measured are treated as components of three-dimensional space vector. Simulative investigations with use of ATP/EMTP package confirm high efficiency of the proposed algorithm.
